I send on uart :04FFF00023001E00CC and after  :08FFF8000003020000000007F5 ,...

I try to program a LPC2148 with a LPC936.
I wrote a little program on the LPC2148.
I can program the LPC936 with a lpc2148.
the crc matches but when I manually add two lines int the hex file, the crc does more than block 1.
I wondered if after a number of data , I dont' must wait or send a command

thanks you

It don't match with the big program but the small it match.
the big program use 6 block and the the small 1 block

hello

I can use by isp with small program of 256 bytes
but with a big program of 28813 bytes it don't work

my hex file is
:102657005387BF7598D353877F75BA01E4F5BD7566
......

and i send
0x2E 0x31 0x30 0x32

where is the problem and why with a small program, it's ok but not with a big?

thank

hello,

I'd like know how flash magic calculs the crc for a lpc9xx on a hex file in cyclic redunbancy check
ex:
:03000000000000FC
:0C002C0078FFE4F6D8FD758107020003A0
:040019007FA07E86C0
:0F001D00EF1F70011E144E600563A00880F222D1
:10000300E4F5A475A5FFF5A063A0FF120019120083
:060013001912001980F231
:00000002FF

the crc for the block 0 : 6EBBF73F

thank you
